...and you need to stop claiming this is a free game. Sure, it's free but you're not going to go anywhere or get anything done unless you pay or spend hours of your valuble time. Time has it's value in itself, so you're paying regardless. So, technically it's free, but not really... And for those of you wanting to (still) be part of this social exeriment, enjoy. PEACE, OUT!
